What’s the Use of an IP Address?
You can think of the IP address as the ID number of the device in the network.
It allows other users to identify and find the device.
With the use of an IP address, you will be able to send files and do other stuff with the computer.
It acts as the specific address of the device.
When you send a file over to a networked device, the computer utilizes the DNS servers to find the hostname and finally the IP address.
For instance, when you enter a website in a browser, the request to load the website goes to the DNS servers that will look up the domain name, and then its corresponding IP address.
Without an IP address, the computer will not be able to find the website.
Different Types of IP Addresses
There are various types of IP addresses. One thing they have in common is that they are made up of letters and numbers.
However, not all IP addresses are used for the same purpose.
The types of IP addresses are private, public, static and dynamic.
Private IP addresses are those used within a network, such as your computers at home.
The computers and devices are all connected to the router, and able to communicate with each other through the private network.
The IP addresses can be set manually or automatically assigned by the home router.
Public IP addresses are those assigned by the internet provider.
It is the maim address of the network that is used to communicate with other devices connected to the internet.
The public IP address allows your computer to connect to the ISP and then to the rest of the world.
Both Private and Public IP addresses can be static or dynamic, which means they can be unchanged or changed respectively.
An IP address that is assigned by a DHCP server is known as a dynamic one.
A static IP is one that is assigned manually, and not assigned by a DHCP server.
